THE EXPERIENCE
What it will actually be like
Only 17% of the Sun is covered, so nothing about the daylight in San Antonio will change. Through a safe solar filter the Moon shows as a shallow notch on one edge of the disc.
SAFETY
Looking at it without hurting yourself
A certified solar filter stays on for the whole eclipse. The Sun is never completely covered here, and what remains is as dangerous to look at as an uneclipsed Sun. Sunglasses are not a filter.
Sunglasses, smoked glass, exposed film and phone screens are not filters. If you can see anything else through it, it is not dark enough.
04 · POSITION
Should I travel?
This eclipse is partial everywhere on Earth — the Moon's dark shadow passes above or below the planet entirely, so there is no path of totality to travel to, from San Antonio or anywhere else.
